The topic in itself for last week was progression raiding, however, only a few of those on the panel (plus the guests) are involved in it.
I know you guys are just getting used to things and it's still a learning process, so hopefully the feedback is just helping you.
But, to talk about "heroic progression as a healer" and not have all sources of information ready at hand isn't being very prepared. Especially if you're (not particularly YOU, even though you're part of the equation :P ) basically the only representation of the class and all of its inhibitions for the topic.
If you can't provide the information needed, then you need to get people who can. Hence why you grabbed some guests. But for starters, they were all 25m raiders. What if you had some 10m heroic raiding questions?
You had... 2 priests? 1 monk and 1 shaman for your guestlist this week? I think you need to get a wider variety.
And I think it may be beneficial to only have 1-2 hosts per podcast, with guests appropriate to the podcast theme. Of which you should have 1 10m raider and 1 25m raider of each class. Level of raiding can vary, as long as their amount of experience is sufficient (which can be dependent on things).
On top of that, there's only like 2-3 people out of what.. 6-7 people talking?
